RAI · interactive mechanism simulation

Vault owners mint RAI against ETH. An on-chain PID controller compares RAI's market price to its own floating redemption price and sets a redemption rate that nudges them back together — no dollar peg to defend. Edit the parameters and watch the control loop run.

Illustrative simulation. Mirrors the researched RAI mechanism (ETH-only CDP vaults, a P-controller-style redemption rate that moves the redemption price toward the market price, and an FLX backstop auction on liquidation shortfall) starting near RAI's real ~$3.14 (pi) launch reference — but ETH price, vault sizes, and timing are randomized for visualization, not live onchain data. Drag the sliders or trigger the ETH crash to see the control loop respond. Part of The Onchain Experiment Atlas.
